摘要

该文介绍并比较了计算机化自适应测验（computerized adaptive testing，CAT）环境中的MLE、WLE、MAP、EAP等几种常用能力估计方法的发展演变以及各自的原理与特性，并对这些能力估计方法的发展脉络及其特性做了简要总结与评价，最后展望了未来CAT中能力估计的发展趋势。%This article introduced the principle and properties of several ability estimator widely used in computerized adaptive testing environment, such as MLE,WLE,MAP&EAP etc. And then, we summed up and appraised the developmental features and properties of these methods. Finally, we try to make several outlooks with regard to the tendency of ability estimation used in Computerized adaptive testing.
